Answer:
Yes a body moving with a constant speed has an acceleration. When an object travel in a circle with a constant speed it's direction keeps changing as a result velocity changing but it works at the centre of the circle therefore acceleration acts at the centre of the circle.
MORE TO KNOW
- Velocity is the distance travelled by an object in a unti time with a specific direction . It is a vector quantity.
- Velocity = Displacement/time
- Ways in which velocity can be change -
- By changing speed
- By changing Direction
- Acceleration is the rate. change of velocity
- Acc = V - U /t
- It is also a vector quantity
- Si unit of velocity = M/S
- Si unit of acceleration = M/S^2
- Average velocity = V + u /2
- U = Initial velocity
- V = Final velocity
- acc = acceleration
- The initial velocity of an object at rest is 0
- The final veloctiy of an object after rest is 0
